Here are the rules: I’ve been at zero a few times, come back a few times, and done it over and over. I’ve started entire new careers. People who knew me then, don’t me now. And so on.
I’ve had to change careers several times. Sometimes because my interests changed. Sometimes because all bridges have been burned beyond recognition, sometimes because I desperately needed money. And sometimes just because I hated everyone in my old career or they hated me.
There are other ways to reinvent yourself, so take what I say with a grain of salt. This is what worked for me.
